The Oracle has chosen this passage for you:
We join spokes together in a wheel, but it is the center hole that makes the wagon move.
We shape clay into a pot, but it is the emptiness inside that holds whatever we want.
We hammer wood for a house, but it is the inner space that makes it livable.
We work with being, but non-being is what we use.
— The Tao Te Ching, Stephen Mitchell translation
